Also, I hope the 240V Ballast mod is fused.

I'll second that. Also if there are any exposed 240 volt terminals you may want to cover them to prevent accidently touching one while doing other fault finding.

I personally would scrap them and any other metal I could find around the house/work. You won't get the top copper price but a lower mixed price maybe around $3 a kilo. Its amazing what they will pay for. On the way to the scrap yard I would stop at a motor re-winders to see if it is economical or possible to rewind them.

I would at least look for someone who would be interested in re winding them.

Also, I hope the 240V Ballast mod is fused.

I helped Adam with this. The ballast is wired to the 240v after the on/off switch which is fused. Doesnt require any further fuses. It is wired before the transformer. So if it overcurrents will blow the line fuse and not damage the transformer.
240v connection is soldered and heatshrinked and wrapped again in electrical tape. No chance of exposing 240v.

Thanks for the reply, Dan. You did an excellent job on X-Files. It now looks like a regular Sega machine as opposed to the Frankenstein job that someone else had done internally with the additional transformer tacked in there.

I've also contacted the transformer company in Melbourne and awaiting a reply on costs of repairing the two fried transformers.

Thank you everyone for your replies!

Cheers!
Adam.
